add synonyms to !top [Distro OR Editor OR ...]

[mlvzk]

Like:

nvim => neovim
arch => Arch Linux

So that results in !top Editor don't have duplicate entries (1. nvim, 4. neovim should be joined into one)

Concept query:

WITH x AS (
    SELECT
        info ->> 'Editor' AS value,
        REPLACE(LOWER(info ->> 'Editor'), 'neovim', 'nvim') AS normalized
    FROM
        sysinfo
    WHERE
        info ->> 'Editor' != ''
),
y AS (
    SELECT DISTINCT ON (normalized)
        value,
        count(*) OVER (PARTITION BY normalized)
    FROM x ORDER BY normalized,
    count DESC
)
SELECT
    *
FROM
    y
ORDER BY
    count DESC
LIMIT 5
